CH Series 4-Channel Power Amplifier

Compact 2U Design: Standard 2U form factor for easy integration into professional audio setups.
Multiple Operating Modes: Choose from three operating modes—STEREO (independent A and B channels), PARALLEL (easy wiring setup), and BRIDGE (high-power amplification)—to suit different application needs.
Comprehensive Protection: Features automatic output limiting, short circuit overload, high-temperature protection, and power-on delay to ensure safe and reliable operation.
Efficient Heat Dissipation: The advanced stepless speed control fan adjusts speed based on radiator temperature, effectively reducing fan noise while ensuring optimal cooling.
User-Friendly Controls: Independent volume control and LED signal level indicator provide clear and convenient monitoring of performance.
Built-In Filtering: Integrated filtering function eliminates high-frequency interference from digital sound and other external equipment.
Enhanced Connectivity: Dual XLR inputs and multiple output options, including SPEAKON and Phoenix terminals, for stronger compatibility across various setups.
Robust Protection Features: Comprehensive safeguards including pressure limit, short circuit, overcurrent, and DC output protection for peace of mind.
